This invention relates .to a casing for loading coils.

Cases for loading coils known hitherto have been frequently constructed in such a manner that the coils or coil pillars were arranged on continuous spindles, for example screwed spindles, and were embedded in a cylindrical casing. This known arrangement has the disadvantage that when one or more coils become defective they cannot be replaced without the entire coil pillar being withdrawn from the case. This makes a severing of the entire coil pillar from the connecting cable necessary. Furthermore, after withdrawing the coil` pillar, a defective coil can only be removed after all coils arranged above the defective coil, on the same spindle, have been removed.

Accordingto this invention these disad vantages are overcome and a coil case particularly adapted for practical use is produced in which the coil pillars are attached to the cover of the casing. All coil pillars are preferably united to form a rigid system by means of transverse plates. Arspecial spindle passed lthrough the coil pillar can therefore be avoided since the s coils are formed into a coil pillar by two or more longitudinal bars arranged at theouter circumference parallel to the axes of thecoils. .'[n the drawings two embodiments ofthe new arrangement are shown; in Fig. l the connecting cables (l.) are passed through holes in the cover l the casing (3). Below thel cover (2) the cables are distributed into separate strands (di) which are spliced with the intermediate cables (9) coming from the coils The coils are attached to longitudinal bars (6) preferably by screws so that they can `lie separately detached.

plates (7 and 8) and the pillars are combined in a rigid system.

The arrangement shown in Fig. 2 differs from that of F ig. l chieiiy only in this, that the cables (l) extend nearly to the bottom of the casing (3). Here they are thendistributed into separate strands and without using a further intermediate cable are directly connected to the coils.

The changing of defective. coils is exceedingly simple with this arrangement. After bars (6) all coil taking off the cover (2) with the block of,

coils attached to it, all coil pillars are per- (2) into theinterior of` By means of the .ing means l .for said members fectly free and remain in their respective positions, so that a disconnecting of the coil pillars from the connecting cable (l) is avoided. Then, from the coil pillar containing the faulty coil and possible after removing one of the longitudinal bars (6) the defectivecoil may be taken out and replaced by another.

The principal advantages of the new arrangement lie in this, that the leading-iu cables (l) can be spliced with the coils (5) before the coil block is embedded in the case, and further, when removing faulty coils, they can be withdrawn and vreplaced without the intermediate cable being removed from the connecting cable before taking out the coil pillar, as if the case with known arrangements.

That is claimed is:

l. A casing `for electromagnetic coils comprising a receptacle, a cover therefor, parallel members grouped in independent pairs and extending within said receptacle for supporting va plurality of electromagnetic coils between members of each of said pairs,

and means for supporting said members .in saidv receptacle from said cover. l

2. A casing for electromagnetic coils ac-` cording to claim 1 in which said supporting means constitutes the receptacle cover, said coils heilig removable therewith.

3. A casing for electromagnetic coils cou-n prising a receptacle, parallel members extending within said receptacle, a plurality of electromagnetic coils'arranged in a pillar adapted to be held between said members, said members partially surrouiuling said coils and being parallel to the axis of said` pillar, and a suspension supporting member on said receptacle for said parallel members.

4. A casing for electromagnetic coils comprising a receptacle, a plurality of coils within` said receptacle arranged in pillars, a plurality of brackets extending parallel to the axes of said coils, each pillar being held betweena pair of brackets, and a suspension supporting means on .said rccei'itacle for said brackets.
